INVESTMENT RETURNS AND PRINCIPAL VALUE WILL FLUCTUATE AND FUND SHARES, WHEN REDEEMED, MAY BE WORTH MORE OR LESS THAN THEIR ORIGINAL COST. The returns shown in this report do not reflect the deduction of taxes that a shareholder would pay on fund distributions or the redemption of fund shares. Performance of share classes will vary due to differences in sales charges and expenses. Average annual total return with sales charges includes payment of the maximum sales charge of 4.75 percent for Class A shares, a contingent deferred sales charge of 4.00 percent for Class B shares (in year one and declining to zero after year five), a contingent deferred sales charge of 1.00 percent for Class C shares in year one, and combined Rule 12b-1 fees and service fees of up to 0.25 percent for Class A shares and up to 1.00 percent for Class B and C shares. The since inception and 10-year returns for Class B shares reflect the conversion of Class B shares into Class A shares six years after purchase. The since inception returns for Class C shares reflect the conversion of Class C shares into Class A shares ten years after purchase. See footnote 3 in the Notes to Financial Statements for additional information. Figures shown above assume reinvestment of all dividends and capital gains. SEC yield is a calculation for determining the amount of portfolio income, excluding non-income items as prescribed by the SEC. Yields are subject to change. Lehman Brothers Corporate Bond Index is a market-weighted index of investment-grade corporate fixed-rate debt issues with maturities of one year or more. Lipper Corporate BBB-Rated Index is an index of funds with similar investment objectives as this fund. Indexes are unmanaged and do not include any sales charges or fees. Such costs would lower performance. It is not possible to invest directly in an index. Source: Lipper Inc. 1 Fund Report FOR THE 6-MONTH PERIOD ENDED FEBRUARY 28, 2005 Van Kampen Corporate Bond Fund is managed by the Adviser's Taxable Fixed Income team.(1) Members of the team include David S. Horowitz, Managing Director of the Adviser. MARKET CONDITIONS The period began in the midst of a slow down in economic recovery brought on by lower-than-expected and downward revisions to prior payroll gains, resulting in a downward trend in yields well into the third quarter. Despite this downward movement, the Federal Reserve Open Market Committee reaffirmed its pledge to raise the federal funds target rate at a measured pace and did so in its meetings through the end of the period. This stance was supported by an increase in economic growth, which picked up steam at the end of 2004. Economic growth continued during the first two months of 2005. The yield curve--which measures the difference in yields between short-, intermediate-and long-maturity Treasuries--flattened further as yields of short- and intermediate-maturity bonds rose while longer-term yields fell. The bulk of the increase in yields occurred in February due, in part, to strong payroll numbers, an upward trend in inflation numbers and testimony by Alan Greenspan indicating an improving economy. The generally optimistic economic environment had a positive effect for corporate bonds. Spreads--which measure the additional yield over Treasuries demanded by investors for assuming credit risk--tightened over the period, though not uniformly. Performance at the sector level varied, with gaming and lodging, energy and insurance among the best-performing sectors of the market. Each sector benefited from improved earnings for key companies within such sector. By contrast, automobile companies and their suppliers were among the worst performers. The electronics sector also suffered. (1)Team members may change without notice at any time. 2 PERFORMANCE ANALYSIS For the six months ending February 28, 2005, the fund's return was 2.93 percent (Class A shares, assuming no front-end sales charge was paid), outperforming the Lehman Brothers Corporate Bond Index and the Lipper Corporate BBB-Rated Index. TOTAL RETURNS FOR THE SIX-MONTH PERIOD ENDING FEBRUARY 28, 2005 <Table> <Caption> - ---------------------------------------------------------------------------- LEHMAN BROTHERS CORPORATE LIPPER CORPORATE CLASS A CLASS B CLASS C BOND INDEX BBB-RATED INDEX 2.93% 2.55% 2.55% 0.90% 2.81% - ---------------------------------------------------------------------------- </Table> THE PERFORMANCE FOR THE THREE SHARE CLASSES VARIES BECAUSE EACH HAS DIFFERENT EXPENSES. THE FUND'S TOTAL RETURN FIGURES ASSUME THE REINVESTMENT OF ALL DISTRIBUTIONS, BUT DO NOT REFLECT THE DEDUCTION OF ANY APPLICABLE SALES CHARGES. SUCH COSTS WOULD LOWER PERFORMANCE. PAST PERFORMANCE IS NO GUARANTEE OF FUTURE RESULTS. SEE PERFORMANCE SUMMARY FOR STANDARDIZED PERFORMANCE INFORMATION AND INDEX DEFINITIONS. The fund's strong performance relative to the Lehman index was driven in large part by its focus on medium-quality corporate securities, which boosted its performance relative to the more broadly constructed Lehman benchmark. Within its portfolio, the fund benefited from an emphasis on the debt of insurance companies, which outperformed strongly for the period. The fund also profited from strong security selection in the paper and energy sectors. The fund's interest-rate posture produced more mixed results for the period. The low level of interest rates across the yield curve at the beginning of the period led us to conclude that they had little room left to fall. As a result, we kept the fund's overall interest-rate exposure well below that of its benchmark. This posture was unfavorable to the fund's returns in those months early in the period when the market rallied, but was more beneficial during periods of rising rates, such as in January and February. There is no guarantee the security sectors mentioned will continue to perform well or be held by the fund in the future. 3 <Table> <Caption> RATINGS ALLOCATIONS AS OF 2/28/05 AAA/Aaa 13.8% AA/Aa 11.8 A/A 20.8 BBB/Baa 42.1 BB/Ba 10.4 B/B 1.1 <Caption> SUMMARY OF INVESTMENTS BY INDUSTRY CLASSIFICATION AS OF 2/28/05 Banking 12.9% U.S. Government Agency Obligations 11.2 Electric 9.6 Automotive 5.9 Noncaptive-Consumer Finance 4.5 Healthcare 4.4 Integrated Energy 4.0 Property & Casualty 3.3 Wireline Communications 3.2 Media-Noncable 3.0 Paper 2.9 Sovereigns 2.8 Food/Beverage 2.5 Media-Cable 1.9 Natural Gas Pipelines 1.8 Noncaptive-Diversified Finance 1.7 Railroads 1.6 Life Insurance 1.5 Lodging 1.5 Entertainment 1.4 Retail 1.4 Brokerage 1.2 Diversified Manufacturing 1.2 Technology 1.1 Gaming 1.1 Construction Machinery 0.9 Chemicals 0.8 Tobacco 0.8 Real Estate Investment Trusts 0.7 Consumer Products 0.7 Pharmaceuticals 0.7 Aerospace & Defense 0.6 Oil Field Services 0.6 Environmental Services 0.5 Independent Energy 0.5 Mortgage-Backed Securities 0.5 Wireless Communications 0.4 Transportation Services 0.4 Airlines 0.4 Textile 0.2 </Table> <Table> (continued on next page) </Table> 4 <Table> <Caption> SUMMARY OF INVESTMENTS BY INDUSTRY CLASSIFICATION AS OF 2/28/05 (continued from previous page) Refining 0.2 Natural Gas Distributors 0.1 ----- Total Long-Term Investments 96.6% Short-Term Investments 5.6 Liabilities in Excess of Other Assets (2.2) ----- Total Net Assets 100.0% </Table> Subject to change daily.

This information is also available on the Securities and Exchange Commission's website at http://www.sec.gov. 7 Expense Example As a shareholder of the Fund, you incur two types of costs: (1) transaction cost, including sales charges (loads) on purchase payments of Class A Shares and contingent deferred sales charge on redemptions of Class B and C Shares; and (2) ongoing costs, including management fees; distribution and service (12b-1) fees; and other Fund expenses. This example is intended to help you understand your ongoing cost (in dollars) of investing in the Fund and to compare these costs with the ongoing costs of investing in other mutual funds. The example is based on an investment of $1,000 invested at the beginning of the period and held for the entire period 09/01/04 - 02/28/05. ACTUAL EXPENSE The first line of the table below provides information about actual account values and actual expenses. You may use the information in this line, together with the amount you invested, to estimate the expenses that you paid over the period. Simply divide your account value by $1,000 (for example, and $8,600 account value divided by $1,000 = 8.6), then multiply the result by the number in the first line under the heading entitled "Expenses Paid During Period" to estimate the expenses you paid on your account during this period. HYPOTHETICAL EXAMPLE FOR COMPARISON PURPOSES The second line of the table below provides information about hypothetical expenses based on the Fund's actual expense ratio and an assumed rate of return of 5% per year before expenses, which is not the Fund's actual return. The hypothetical account values and expenses may not be used to estimate the actual ending account balance or expenses you paid for the period. You may use this information to compare the ongoing cost of investing in the Fund and other funds. To do so, compare this 5% hypothetical example with the 5% hypothetical examples that appear in the shareholder reports of the other funds. Please note that the expenses shown in the table are meant to highlight your ongoing costs only and do not reflect any transactional costs, such as sales charges (loads) or contingent deferred sales charges. Therefore, the second line of the table is useful in comparing ongoing costs only, and will not help you determine the relative total costs of owning different funds. In addition, if these transactional costs were included, your costs would have been higher. <Table> <Caption> BEGINNING ENDING EXPENSES PAID ACCOUNT VALUE ACCOUNT VALUE DURING PERIOD* ------------------------------------------------ 9/1/04 2/28/05 9/1/04-2/28/05 Class A Actual...................................... $1,000.00 $1,029.25 $4.78 Hypothetical................................ 1,000.00 1,020.09 4.76 (5% annual return before expenses) Class B Actual...................................... 1,000.00 1,025.50 8.59 Hypothetical................................ 1,000.00 1,016.29 8.55 (5% annual return before expenses) Class C Actual...................................... 1,000.00 1,025.50 8.19 Hypothetical................................ 1,000.00 1,016.69 8.15 (5% annual return before expenses) </Table> * Expenses are equal to the Fund's annualized expense ratio of 0.95%, 1.71%, and 1.63% for Class A, B, and C Shares, respectively, multiplied by the average account value over the period, multiplied by 181/365 (to reflect the one-half year period).

These returns include combined Rule 12b-1 fees and service fees of up to 1% and do not reflect the deduction of taxes that a shareholder would pay on Fund distributions or the redemption of Fund shares. (c) As required, effective September 1, 2001, the Fund has adopted the provisions of the AICPA Audit and Accounting Guide for Investment Companies and began amortizing premium on fixed income securities. The effect of this change for the year ended August 31, 2002, was to decrease net investment income per share by $.03, increase net realized and unrealized gains and losses per share by $.03 and decrease the Ratio of Net Investment Income to Average Net Assets by .52%. Per share, ratios and supplemental data for periods prior to August 31, 2002, have not been restated to reflect this change in presentation. (d) The Total Return, Ratio of Expenses to Average Net Assets and Ratio of Net Investment Income to Average Net Assets reflect actual 12b-1 fees of less than 1% (See Footnote 6). (e) Amount is less than $.01. See Notes to Financial Statements 23 VAN KAMPEN CORPORATE BOND FUND NOTES TO FINANCIAL STATEMENTS -- FEBRUARY 28, 2005 (UNAUDITED) 1. SIGNIFICANT ACCOUNTING POLICIES Van Kampen Corporate Bond Fund (the "Fund") is organized as a Delaware statutory trust, and is registered as a diversified open-end management investment company under the Investment Company Act of 1940 (the "1940 Act"), as amended. The Fund's primary investment objective is to seek to provide current income with preservation of capital. The Fund commenced investment operations on September 23, 1971. The distribution of the Fund's Class B and Class C Shares commenced on September 28, 1992 and August 30, 1993, respectively. The Fund registered Class I shares on September 1, 2004. There were no sales of Class I shares for the period ended February 28, 2005. The following is a summary of significant accounting policies consistently followed by the Fund in the preparation of its financial statements. The preparation of financial statements in conformity with U.S. generally accepted accounting principles requires management to make estimates and assumptions that affect the reported amounts of assets and liabilities and disclosure of contingent assets and liabilities at the date of the financial statements and the reported amounts of revenues and expenses during the reporting period. Actual results could differ from those estimates. A. SECURITY VALUATION Fixed income investments are stated at value using market quotations or indications of value obtained from an independent pricing service. Investments in securities listed on a securities exchange are valued at their last sale price as of the close of such securities exchange. Listed and unlisted securities for which the last sales price is not available are valued at the mean of the bid and asked prices. For those securities where quotations or prices are not available as noted above, valuations are determined in accordance with procedures established in good faith by the Board of Trustees. Futures contracts are valued at the settlement price established each day on the exchange in which they are traded. Short-term securities with remaining maturities of 60 days or less are valued at amortized cost, which approximates market value. B. SECURITY TRANSACTIONS Security transactions are recorded on a trade date basis. Realized gains and losses are determined on an identified cost basis. The Fund invests in repurchase agreements, which are short-term investments in which the Fund acquires ownership of a debt security and the seller agrees to repurchase the security at a future time and specified price. The Fund may invest independently in repurchase agreements, or transfer uninvested cash balances into a pooled cash account along with other investment companies advised by Van Kampen Asset Management (the "Adviser") or its affiliates, the daily aggregate of which is invested in repurchase agreements. Repurchase agreements are fully collateralized by the underlying debt security. The Fund will make payment for such securities only upon physical delivery or evidence of book entry transfer to the account of the custodian bank. The seller is required to maintain the value of the underlying security at not less than the repurchase proceeds due the Fund. C. INCOME AND EXPENSES Interest income is recorded on an accrual basis. Discounts on debt securities purchased are accreted and premiums are amortized over the expected life of each applicable security. Income and expenses of the Fund are allocated on a pro rata basis to each class of shares, except for distribution and service fees and incremental transfer agency costs which are unique to each class of shares. 24 VAN KAMPEN CORPORATE BOND FUND NOTES TO FINANCIAL STATEMENTS -- FEBRUARY 28, 2005 (UNAUDITED) continued D. FEDERAL INCOME TAXES It is the Fund's policy to comply with the requirements of Subchapter M of the Internal Revenue Code applicable to regulated investment companies and to distribute substantially all of its taxable income to its shareholders. Therefore, no provision for federal income taxes is required. The Fund intends to utilize provisions of the federal income tax laws which allow it to carry a realized capital loss forward for eight years following the year of the loss and offset these losses against any future realized capital gains. At August 31, 2004, the Fund had an accumulated capital loss carryforward for tax purposes of $18,983,081 which will expire according to the following schedule: <Table> <Caption> AMOUNT EXPIRATION $ 831,968.................................................

DISTRIBUTION OF INCOME AND GAINS The Fund declares daily and pays monthly dividends from net investment income. Net realized gains, if any, are distributed annually. Distributions from net realized gains for book purposes may include short-term capital gains and gains on future transactions. All short-term capital gains and a portion of future gains are included in ordinary income for tax purposes. The tax character of distributions paid during the fiscal year ended August 31, 2004 was as follows: <Table> <Caption> 2004 Distribution paid from: Ordinary Income........................................... $25,453,701 Long-term capital gain.................................... -- Return of Capital......................................... 204,800 ----------- $25,658,501 =========== </Table> Net realized gains or losses may differ for financial and tax reporting purposes as a result of the deferral of losses relating to wash sale transactions. F. EXPENSE REDUCTIONS During the six months ended February 28, 2005, the Fund's custody fee was reduced by $10,476 as a result of credits earned on cash balances. 25 VAN KAMPEN CORPORATE BOND FUND NOTES TO FINANCIAL STATEMENTS -- FEBRUARY 28, 2005 (UNAUDITED) continued 2. INVESTMENT ADVISORY AGREEMENT AND OTHER TRANSACTIONS WITH AFFILIATES Under the terms of the Fund's Investment Advisory Agreement, the Adviser will provide investment advice and facilities to the Fund for an annual fee payable monthly as follows: <Table> <Caption> AVERAGE DAILY NET ASSETS % PER ANNUM First $500 million.......................................... .42% Next $750 million........................................... .35% Over $1.250 billion......................................... .22% </Table> Effective November 1, 2004, the management fee was reduced from .50% for the first $150 million, .45% for the next $100 million, .40% for the next $100 million, and .35% for any average daily net assets greater than $350 million. For the six months ended February 28, 2005, the Fund recognized expenses of approximately $21,300 representing legal services provided by Skadden, Arps, Slate, Meagher & Flom LLP, counsel to the Fund, of which a Trustee of the Fund is a partner of such firm and he and his law firm provide legal services as legal counsel to the Fund. Under an Accounting Services agreement, the Adviser provides accounting services to the Fund. The Adviser allocates the cost of such services to each fund. For the six months ended February 28, 2005, the Fund recognized expenses of approximately $17,100 representing Van Kampen Investments Inc.'s or its affiliates (collectively "Van Kampen") cost of providing accounting services to the Fund, which are reported as part of "Other" expenses in the Statement of Operations. Van Kampen Investor Services Inc. (VKIS), an affiliate of the Adviser, serves as the shareholder servicing agent for the Fund. For the six months ended February 28, 2005, the Fund recognized expenses of approximately $474,800 representing transfer agency fees paid to VKIS. Transfer agency fees are determined through negotiations with the Fund's Board of Trustees. Certain officers and trustees of the Fund are also officers and directors of Van Kampen. The Fund does not compensate its officers or trustees who are also officers of Van Kampen. The Fund provides deferred compensation and retirement plans for its trustees who are not officers of Van Kampen. Under the deferred compensation plan, trustees may elect to defer all or a portion of their compensation. Amounts deferred are retained by the Fund and, to the extent permitted by the 1940 Act, as amended, may be invested in the common shares of those funds selected by the trustees. Investments in such funds of approximately $77,800 are included in "Other" assets on the Statement of Assets and Liabilities at February 28, 2005. Appreciation/depreciation and distributions received from these investments are recorded with an offsetting increase/decrease in the deferred compensation obligation and do not affect the net asset value of the Fund. Benefits under the retirement plan are payable upon retirement for a ten-year period and are based upon each trustee's years of service to the Fund. The maximum annual benefit per trustee under the plan is $2,500. 26 VAN KAMPEN CORPORATE BOND FUND NOTES TO FINANCIAL STATEMENTS -- FEBRUARY 28, 2005 (UNAUDITED) continued 3.

INVESTMENT TRANSACTIONS During the period, the cost of purchases and proceeds from sales of investments, excluding short-term investments, were $223,541,553 and $151,085,671, respectively. 5. DERIVATIVE FINANCIAL INSTRUMENTS A derivative financial instrument in very general terms refers to a security whose value is "derived" from the value of an underlying asset, reference rate or index. The Fund has a variety of reasons to use derivative instruments, such as to attempt to protect the Fund against possible changes in the market value of its portfolio or to generate 28 VAN KAMPEN CORPORATE BOND FUND NOTES TO FINANCIAL STATEMENTS -- FEBRUARY 28, 2005 (UNAUDITED) continued potential gain. All of the Fund's portfolio holdings, including derivative instruments, are marked to market each day with the change in value reflected in unrealized appreciation/depreciation. Upon disposition, a realized gain or loss is recognized accordingly, except when taking delivery of a security underlying a futures contract. In this instance, the recognition of gain or loss is postponed until the disposal of the security underlying the futures contract. Risk may arise as a result of the potential inability of the counterparties to meet the terms of their contracts. During the period, the Fund invested in futures contracts, a type of derivative. A futures contract is an agreement involving the delivery of a particular asset on a specified future date at an agreed upon price. The Fund generally invests in futures on U.S. Treasury Notes. Upon entering into futures contracts, the Fund maintains an amount of cash or liquid securities with a value equal to a percentage of the contract amount with either a futures commission merchant pursuant to rules and regulations promulgated under the 1940 Act, as amended, or with its custodian in an account in the broker's name. This amount is known as initial margin. During the period the futures contract is open, payments are received from or made to the broker based upon changes in the value of the contract (the variation margin). The risk of loss associated with a futures contract is in excess of the variation margin reflected on the Statement of Assets and Liabilities. Transactions in futures contracts for the six months ended February 28, 2005, were as follows: <Table> <Caption> CONTRACTS Outstanding at August 31, 2004.............................. 845 Futures Opened.............................................. 2,490 Futures Closed..............................................

DISTRIBUTION AND SERVICE PLANS With respect to its Class A Shares, Class B Shares and Class C Shares, the Fund and its shareholders have adopted a distribution plan pursuant to Rule 12b-1 under the 1940 Act, as 29 VAN KAMPEN CORPORATE BOND FUND NOTES TO FINANCIAL STATEMENTS -- FEBRUARY 28, 2005 (UNAUDITED) continued amended, and a service plan (collectively, the "Plans"). The Plans govern payments for: the distribution of the Fund's Class A Shares, Class B Shares and Class C Shares; the provision of ongoing shareholder services with respect to such classes of shares; and the maintenance of shareholder accounts with respect to such classes of shares. Annual fees under the Plans of up to .25% of Class A average daily net assets and up to 1.00% each of Class B and Class C average daily net assets are accrued daily. The annual fees for Class A Shares are paid quarterly and the annual fees for Class C Shares are paid monthly. For Class B Shares, 75% of the annual fees are paid monthly, while 25% of the annual fees are paid quarterly. The amount of distribution expenses incurred by Van Kampen and not yet reimbursed ("unreimbursed receivable") was approximately $2,050,900 and $0 for Class B and Class C Shares, respectively. These amounts may be recovered from future payments under the distribution plan or CDSC. To the extent the unreimbursed receivable has been fully recovered, any excess 12b-1 fees will be refunded to the Fund on a quarterly basis. Included in the fees for the six months ended February 28, 2005, are payments retained by Van Kampen of approximately $501,400 and payments made to Morgan Stanley DW Inc., an affiliate of the Adviser, of approximately $111,600. 7. LEGAL MATTERS The Adviser, certain affiliates of the Adviser, and certain investment companies advised by the Adviser or its affiliates, including the Fund, are named as defendants in a number of similar class action complaints which were recently consolidated. This consolidated action also names as defendants certain individual Trustees and Directors of certain investment companies advised by affiliates of the Adviser; the complaint does not, however, name the individual Trustees of any Van Kampen funds. The consolidated amended complaint generally alleges that defendants violated their statutory disclosure obligations and fiduciary duties by failing properly to disclose (i) that the Adviser and certain affiliates of the Adviser allegedly offered economic incentives to brokers and others to steer investors to the funds advised by the Adviser or its affiliates rather than funds managed by other companies, and (ii) that the funds advised by the Adviser or its affiliates, including the Fund, allegedly paid excessive commissions to brokers in return for their alleged efforts to steer investors to these funds. The complaint seeks, among other things, unspecified compensatory damages, rescissionary damages, fees and costs. The Adviser and certain affiliates of the Adviser are also named as defendants in a derivative suit which additionally names as defendants certain individual Trustees of certain Van Kampen funds; the named investment companies, including the Fund, are listed as nominal defendants. The complaint alleges that defendants caused the Van Kampen funds to pay economic incentives to a proprietary sales force to promote the sale of proprietary mutual funds. The complaint also alleges that the Van Kampen funds paid excessive commissions to Morgan Stanley and its affiliates in connection with the sales of the funds. The complaint seeks, among other things, the removal of the current Trustees of the funds, rescission of the management contracts for the funds, disgorgement of profits by Morgan Stanley and its affiliates and monetary damages. This complaint has been coordinated with the consolidated complaint described in the preceding paragraph. Plaintiff has sought leave to file a second amended derivative compliant that alleges that the Adviser permitted or recklessly disregarded market timing and late trading in its proprietary mutual funds in order 30 VAN KAMPEN CORPORATE BOND FUND NOTES TO FINANCIAL STATEMENTS -- FEBRUARY 28, 2005 (UNAUDITED) continued to increase assets under management and fees. However, pursuant to an agreement between the parties, that plaintiff's proposed second amended derivative complaint was withdrawn and the allegations regarding market timing and late trading asserted therein were filed in a separate complaint and coordinated with other cases related to market timing that have been centralized in a federal court. The defendants have moved to dismiss each of these actions and otherwise intend to defend them vigorously. While the defendants believe that they have meritorious defenses, the ultimate outcome of these matters is not presently determinable at this early stage of litigation, and no provision has been made in the Fund's financial statements for the effect, if any, of these matters. 8. INDEMNIFICATIONS The Fund enters into contracts that contain a variety of indemnifications. The Fund's maximum exposure under these arrangements is unknown. However, the Fund has not had prior claims or losses pursuant to these contracts and expects the risk of loss to be remote. 31 VAN KAMPEN CORPORATE BOND FUND BOARD OF TRUSTEES AND IMPORTANT ADDRESSES BOARD OF TRUSTEES DAVID C.
